Smartphones are getting boring. The new models are either a bit faster or have better cameras, but they are basically no different from the ones already in our pockets. This is why scientists are hoping, and working for something new, something that will change our lives just as greatly as smartphones do. At the moment, the next invention might be smart glasses.
Just imagine. Instead of having to pick up your phone and look at the screen, all of the information you need simply appears just in front of you, in your glasses. Satellite navigation (导航) directions would appear right there on the road. And your smart glasses could guide you to the right shelf in the supermarket!
Smart glasses could also be used in industry. They could show engineers the instructions they need to fix things more quickly. A doctor could carry out a difficult operation, guided in real time by someone on the other side of the world.
This may sound impossible. But most of the technologies to invent them are already there. For example, one key technology is called AR, which can make digital 3D objects appear as if they are part of the real world. We’ve used it a lot on our video calls. Similarly, huge progress has been made in spatial audio. This is when a sound is made to give it a sense of place, like what you hear in an empty room. Some high-end earphones can already do that. Future glasses will of course need to recognize (识别) your voice to do tasks. This technology has been widely used in our daily life.
So, why aren’t we all wearing smart glasses yet? So far, no one has invented a good way to send images (映像) of our world onto glasses. However, with the rapid development of technology, smart glasses could arrive much sooner than we think.

【推荐1】How do you deal with plastic bags from the supermarket? Throw them away or reuse them? How about eating them?
EnviGreen in India has made a bag with natural ingredients (成分). It looks and feels just like plastic, but can be broken down. The bags bring no harm to the environment. Both humans and animals can safely eat them. EnviGreen’s founder Ashwath Hedge spent four years trying out such a thing of 12 natural ingredients. It includes potatoes, vegetable oil and bananas. He made the ingredients into liquid (液体) and used the liquid to make the bag.
Although the EnviGreen bags are much more expensive than those usual plastic bags, they are good for our environment. Usually, it takes 1, 000 years for usual plastic bags to break down. But an EnviGreen bag can naturally break down in less than 180 days. It also breaks down in less than a day in water, and in about 15 seconds in boiling water. Maybe the EnviGreen bag could be a solution to the world problem of plastic pollution.

【推荐3】It’s common to carry things on bikes, trains and even planes. But do you know small drones（无人机）can help carry packages to your home? For two years, Google has been working hard in their secret research lab. They have made great progress. Their latest project is called Project Wing. Project Wing is Google’s invention of a drone delivery（运送） service. It is half plane and half helicopter （直升机） and is slightly bigger than a seagull（海鸥）. It can deliver packages to customers’ doors.
The best thing about drone delivery services is that delivery time will be greatly cut down. You’ll be able to order online in the morning. And by noon, the delivery drone will deliver you package.
Interestingly, drones are not that young. The USA has been using armed（武装）drones since 2002. But drones may also get another use. Film companies have asked to use drones to shoot videos from the sky.
Google’s delivery drones won’t be able to fly to customers any time soon. However, Google has proved that drone delivery is possible. And with Amazon announcing their drone delivery service last year, the heat is on to make safe and suitable drones to fly the skies for customers.
1. What is Project Wing?| A．Half plane. | B．A drone delivery service. | C．Google’s invention of searching. |
| A．One year. | B．Two years | C．Three years. |
| A．education | B．film | C．delivery |

Building a country is never easy. But how about making one disappear? A new report said a long time of climate (气候) change could do that. It also said Tuvalu would be the first country to be completely lost because of climate change.
Tuvalu, a Pacific island country with many small islands, is near Australia, lying in the South Hemisphere (南半球) and there are only 12,000 people in this country. Now, 40 percent of the area in its capital is underwater.
▲ . They don’t want to lose their country, so they plan to build a new one in the metaverse (元宇宙). It is a digital (数字化) country that only shows online. No matter where Tuvalu people live in the real world, they will still have their nationality (国籍) and “live” in its online country. For example, if a Tuvaluan misses the beautiful butterflies and the soft wind in their hometown, he can enter their digital country online and enjoy them.
This news made people in Tuvalu excited. But Li Zuxi, a director of the metaverse lab, said, “Though the digital country belongs to Tuvalu, it’s built on a metaverse platform (平台). Now, the metaverse is not perfect, which may bring some problems. He gave us an example. If someone from other countries enters the space of the digital country, how can the system tell if the person truly belongs to that country. In such situations, the safety of this digital country can’t be made sure of.”
However, many island countries disagree with Li Zuxi. They say that building a digital country may be new, but this is the only way for people in those island countries to be connected. Why not have a try?
Actually, whether people will build it or not, saving the real world and creating a better living environment should be paid the most attention to.
1. From the picture, Tuvalu lies in the place of ________.| A．L1 | B．L2 | C．L3 | D．L4 |
| A．The government of Tuvalu hasn’t done enough to save the country |
| B．Whether the country will disappear depends on how Tuvalu people protect the environment |
| C．People from all over the world are trying to save Tuvalu from disappearing |
| D．Facing the disappearing of their country, all Tuvalu people are so sad |

【推荐2】China has completed its BeiDou Navigation Satellite System (北斗卫星导航系统), or BDS. It becomes a new system in the world with a global navigation network (全球导航网络). The other three systems are GPS of the US, GLONASS of Russia and Galileo of the European Union.
As the name suggests, the global navigation satellite system provides navigation and location services 24 hours a day. As we know, building a good satellite system costs a lot. Besides, the other systems have been set up. Why does China have a new one if there is nothing special?
The other three systems have 24 satellites. China’s BDS has six more satellites. What’s special about these six satellites is that they have a relatively fixed area of activity. This can improve BDS’ accuracy (精准度) in China and the Asia-Pacific region to 5 meters, compared with a 10-meter accuracy in other areas.
BDS has another advantage-the short message service. It allows users to have a two-way communication. In areas that are not covered by communication signals (信号), users can send short messages. Even in uninhabited areas, such as deserts, forests, mountainous and polar areas, BDS can also make the short message service available. With this service, users who are in danger can tell the rescue team (救援队) their location and condition.
As the most populous country, it’s important for China to have its own global navigation satellite system to meet the needs of the country’s development. In fact, BDS is also good business. According to the official report, China’s satellite industry has kept a 20% yearly growth since 2012. And BDS contributes about 80% of it. In addition, BDS has also created countless high-paying jobs. And with continuous improvement, it will have much more to offer in the future.
1. Which one is the global navigation satellite system of China?| A．BDS. | B．GPS of the US. | C．GLONASS of Russia. |
| A．6. | B．24. | C．30. |
| A．人口众多的 | B．无人居住的 | C．风平浪静的 |
a. It has met the needs of China’s development.

【推荐3】①Every now and then you may see news of satellites sent into space. On Feb 21, for example, US company Space X took 46 satellites into orbit. On Feb 27, China sent 22 satellites into space. Why do we need so many satellites? What do they do out there?
②At present, there are more than 3,000 satellites moving around the Earth, according to Germany. Satellites are very helpful to humans. They do all kinds of work, from transmitting (传送) TV signals to giving you directions on the road to helping scientists do research.
③For example, the 22 satellites China just sent up are part of the Beidou Navigation Satellite System. Shared bikes that use BeiDou chips can be easier to find. Drones (无人机) can also use BeiDou to fly.
④Before satellites, TV signals didn’t go very far. Mountains or tall buildings would stop them. Phone calls to faraway places were also a problem. With satellites, TV signals and phone calls can be sent directly to a satellite and back down to different places on Earth.
⑤Satellites can also provide information about clouds, oceans, land and ice. They help scientists predict changes in weather. By monitoring (监测) wildfires and volcanoes, satellites help people deal with natural disasters. Farmers can use satellite pictures to decide the best time to water their fields.
⑥Some satellites fly near other planets. They may look for water on Mars or take close-up pictures of Saturn’s rings (土星环). In 2020, Bilibili sent a satellite into space. Its job is to look at other planets and share the pictures and videos with Bilibili’s users.

Dubai is a city of big business, expensive hotels, skyscrapers (摩天楼), and shopping malls. In the early 20th century, Dubai was a successful trading port. People from the world stopped in Dubai to do business. But it was still a small city, and most people lived as fishermen and businessmen. Then in 1966, oil was discovered. This brought a lot of money into the area, and soon Dubai began to change.
Today Dubai is one of the world’s most important business centers. In fact, each year the city gets its money mainly from business, not oil.
________ They come to relax on its beaches, and every year, millions of people visit just for visit or just to go shopping!
Dubai is also one of the world’s fastest growing cities. Many tall buildings are built in months. The city also has many man-made islands. One of these, the Palm Jumeirah, looks like a palm tree (棕榈树) and is very beautiful.
The city is still an amazing mix (混合体) of people from different countries. People from 150 countries live and work in Dubai, and foreigners now outnumber Dubai natives (本地人) by eight to one!
Many people welcome the city’s growth. But an increasing number of Dubai natives worry about the speed of change. As a Dubai native says, “We must always remember where we came from. Our kids must know we worked very, very hard to get where we are now, and there’s much more work to do.”

【推荐2】If I had a cold, I wouldn’t think twice about telling my friends or my doctor. For some reason, however, mental (心理的) health is not treated in the same way.
At my primary school, mental health was not discussed even once as far as I can remember. This makes me wonder how many other schools are failing to educate their students on this topic. It makes me sad that children growing up with mental illness may feel like it is something to be ashamed of (对……感到羞耻的) because it is never discussed. When I reached high school, mental health was still seldom discussed. But when it was in the topic of health or biology class, I was given a broad idea that mental illness was a “thing” that really lies.
In my opinion, overstressed high school students could benefit (获益) greatly from more deep discussions about how to deal with mental health problems, such as how to know when you should care about yourself or a friend, or who to reach out for help. I know my friends and I could have (本可以) benefited. Even if you personally have never faced mental health problems, someone you know is sure to have, and you can offer timely help.
I believe we need to normalize (使……正常化) discussions about mental health at an early age, rather than hiding them from sight. At school, I saw a student’s report on mental health education and how it can be carried out in the American school system. The student used the film Inside Out (头脑特工队) to explain feelings to younger kids. This report made me believe that it is possible to start these discussions at a young age if we try.
Although we can’t change the way people think about mental health over one night, there are still things we can do. Asking our friends how they’re feeling is a good start.

The Erie Canal was the first important national waterway built in the US. It crossed New York State（州）from Buffalo on Lake Eric to Albany on the Hudson River. It joined the Great Lakes with the Atlantic Ocean.
Over the canal industrial goods（工业产品）could flow into the west, and materials could pour into the east. The Erie Canal helped New York develop into the nation's larges city.
The building of the canal was paid for completely by the state of New York. It cost $7,143,789, but it soon gained its price many times over. Between 1825, when the canal was opened, and 1882, when toll charges（过运河费）were stopped, the state collected $121,461,891.
For a hundred years before the Erie Canal was built, people had been talking about a canal to join the Great Lakes and the Atlantic Ocean. The man who planned the Erie Canal and carried the plan through was De Witt Clinton. At that time some people laughingly called it "Clinton's Ditch（沟）". Clinton talked and wrote about the canal and drew up plans for it. He and Governor Morris went to Washington in 1812 to ask for help for the canal, but they were unsuccessful.
Clinton became governor of New York State in 1817, and shortly afterwards, on July 4,1817, broke ground for the canal in Rome of New York State. The first part of the canal was completed in 1820. As the canal grew, towns along its course developed fast. The length of the canal is 363 miles.
